Propylene Glycol Food Grade — USP Grade / CAS 57-55-6

Description

1. Product Overview

Propylene Glycol Food Grade (USP Grade, CAS 57-55-6) is a high-purity, multifunctional organic diol widely used across food, pharmaceutical, and industrial applications. It serves as a humectant, solvent, carrier, and stabilizer, ensuring product consistency, moisture retention, and enhanced formulation stability. Its USP-grade certification guarantees compliance with stringent global safety and quality standards for direct and indirect food-contact applications.

Strategically, Propylene Glycol is a critical input in modern manufacturing due to its versatility, non-toxic profile, and compatibility with a wide range of formulations. It is a preferred substitute for more hazardous glycols, offering safer handling and regulatory acceptance across international markets.
